In the Arms of the Vampire (Monster Sex)

Rachel regrets letting a guy at the club she's in buy her a drink. She just wanted the drink, not the grinding her gave her afterward. Then another man, handsome and nice, comes to her rescue. He gets her a drink, too. Rachel needs to remember that nothing is free. It turns out that her dancing partner is a vampire. He wants one thing: her flesh. Rachel discovers that she wants to give it to him.
